Introduction
Many 1930s Westclox Big Ben and Baby Ben alarm clocks were repainted over the years, often with thick black coatings that hide the original factory finish. Restoring these cases requires careful paint removal, metal surface preparation, and protection of the dial and movement. This guide explains how to safely strip unwanted paint, evaluate the underlying finish, and restore the clock’s appearance while preserving original components.
Evaluating the Case Before Restoration
Identify the model and era
Determine whether the clock is a Big Ben Style 5, early Style 6, or a related Baby Ben model to understand the original finish.
Check for factory paint
Some clocks were originally painted; others had plated or lacquered finishes. Knowing the original surface guides restoration choices.
Assess repaint thickness
Thick brush-applied paint may hide dents, corrosion, or plating loss.
Inspect metal condition
Look for rust, pitting, or peeling plating beneath the paint.
Evaluate dial and bezel fit
Ensure the bezel closes properly and the dial is not stressed by case distortion.
Removing Old Paint
Test a small area first
Use a mild solvent or stripper on a hidden spot to determine how the paint reacts.
Avoid harsh chemicals
Strong strippers can damage plating or original lacquer beneath the repaint.
Use controlled scraping
Plastic scrapers help lift paint without gouging the metal.
Work slowly
Remove paint in thin layers to avoid damaging the underlying finish.
Clean residue
Use mild cleaners to remove remaining paint without harming the metal surface.
Preparing the Metal Surface
Assess plating condition
Determine whether the original nickel or brass plating is intact or worn through.
Remove rust
Use fine abrasives or rust removers suitable for thin-gauge metal.
Smooth imperfections
Light sanding can reduce pitting or uneven areas.
Decide on refinishing
Choose between repainting, polishing, or preserving the aged finish.
Clean thoroughly
Ensure the case is free of dust and oils before applying any finish.
Protecting the Dial and Movement
Remove the movement
Take the movement out before stripping or sanding to avoid contamination.
Store the dial safely
Paper and metal dials can be damaged by solvents, dust, or moisture.
Protect the hands
Hands bend easily; store them flat and away from tools.
Inspect the alarm mechanism
Ensure the alarm lever, hammer, and gears are clean and functional.
Reinstall carefully
Verify that the movement seats properly and the bezel closes without pressure.
Refinishing Options
Repainting the case
Use enamel or lacquer paints to replicate original factory colors.
Preserving patina
Light cleaning and waxing can maintain an aged, authentic appearance.
Polishing metal
Nickel or brass surfaces can be polished if plating is intact.
Replacing missing hardware
Match screws, feet, and knobs to original Westclox designs.
Final assembly
Reinstall the movement, dial, and hands once the finish has cured.
Troubleshooting
Paint won’t lift
Repaint too thick → Solvent too weak → Work in thinner layers
Metal shows deep pitting
Corrosion advanced → Requires filling or repainting
Bezel won’t close
Case distortion → Dial misaligned → Bezel ring bent
Finish looks uneven
Poor surface prep → Inconsistent sanding → Residual paint
Movement doesn’t seat properly
Case shifted → Mounting points worn → Incorrect reinstallation
Common Mistakes to Avoid
Using harsh strippers
These can damage plating or original lacquer.
Over-sanding thin metal
Too much abrasion can deform the case.
Leaving the movement installed
Dust and chemicals can damage delicate components.
Skipping test patches
Always test solvents before full application.
Rushing refinishing
Proper curing ensures a durable, even finish.
Checklist for Final Verification
• Paint fully removed
• Metal surface clean and stable
• Plating assessed and preserved
• Dial and hands protected
• Movement reinstalled correctly
• Bezel closes smoothly
• Finish even and appropriate for the era
FAQs
Was the original Big Ben case painted?
Some were painted; others were plated or lacquered depending on the model and year.
Can the original finish be saved?
Often yes, if the repaint was applied over intact plating.
Is repainting acceptable?
Yes—especially when the original finish is too damaged to preserve.
Why does the bezel not close?
Case distortion or dial misalignment often causes interference.
How often should these clocks be serviced?
Every 5–7 years depending on use and environment.
